Abstract:
Objective To evaluate carbon lymph tracer (CH40) in pancreatic cancer surgery.Method 61cases of pancreas head carcinoma undergoing whipple procedure from June 2011 to December 2013 were divided into intraoperative nano carbon group (group A,36 cases),in which resection range was adjusted according to lymph node staining including 13 standard resection cases (group A1),and 23 modified extended radical resection cases (group A2).Standard group (group B,n =17),and extended radical operation group (group C,n =8),respectively.Results The average lymph nodes harvested in group A1 were 25.08 ± 2.72,with positive lymph nodes of 7.92 ± 2.22,significantly more than group B (19.47±1.55,2.68 ±5.24),P＜0.05.In group A2,the average lymph node was 29.91 ±2.68,positive lymph node was 11.04 ± 2.38,significantly more than group C (25.13 ± 2.85,8.49 ± 3.32),P ＜0.05.The mean survival time and overall survival time of group A1 were 43.80 ±4.09 months,51.44 ±1.64 months,significantly more than group B (27.11 ±3.36,41.74 ±3.28 months),P ＜0.05.In group A2,the average tumor free survival time,and overall survival time was 31.58 ±2.99 months,45.02 ±2.54 months,not statistically different with group C (29.13±4.76 month,43.67 ±3.33 months),P ＞0.05.Conclusions Intraoperative lymphatic tracer technology significantly increases lymph node harvest,improving the survival time and tumor free prognosis.
